Understand Global Warming

Global warming is the long-term rise in the average temperature of the Earth‘s climate system. It is a major aspect of climate change, and has been demonstrated by direct temperature measurements and by measurements of various effects of the warming.

The terms global warming and climate change are often used interchangeably. However, speaking more accurately, global warming denotes the mainly human-caused increase in global surface temperatures and its projected continuation, but climate change includes both global warming and its effects, such as changes in precipitation.

While there have been prehistoric periods of global warming, many observed changes since the mid-20th century have been unprecedented over decades to millennia. (Wikipedia, 2019)

Why we need to reduce CO2 emission?

Carbon dioxide (CO2) accounts for the highest proportion of greenhouse gases (about 82%), human activities release CO2 significantly, such as deforestation and burning of fossil fuels.

According to NASA measurements, the current average global carbon dioxide level will reach 420ppm (parts per million), and the number will continue to rise. Global temperature has been increased by 1.9 degrees Fahrenheit since 1880. Ice and snow have melted by about 12.8% over the past 100 years.

One kilowatt-hour creates 1.13 pounds of carbon dioxide. If you consume 10,000 kilowatt-hours in a year, you’ll generate 5.65 short tons of carbon dioxide. (Blueskymodel 2019)  Ref: Clayton, J. (2019). 1 kilowatt-hour · BlueSkyModel. Retrieved 11 December 2019, from blueskymodel

On average, every 6.6 kWh system in Queensland can generate 30 kW each day, that means:

  • You can save 30 kW a day and reduce 33.9 pounds of CO2 emission per day.
  • You can save 10950 kW a year and reduce 6.18 short tons of CO2 emission per year.
